Answer:

The correct option is B.

Step-by-step explanation:

From the given graph it is clear the x-coordinate of the vector is 3 and y-coordinate of the vector is 4 in the coordinate plane.

The given vector can be defined as

[tex]A=\begin{bmatrix}3 & 4\end{bmatrix}[/tex]

Translation vector is

[tex]B=\begin{bmatrix}0 & -1\\ 1 & 0\end{bmatrix}[/tex]

We need to find the resulting vector,

[tex]AB=\begin{bmatrix}3 & 4\end{bmatrix}\cdot \begin{bmatrix}0 & -1\\ 1 & 0\end{bmatrix}[/tex]

[tex]AB=\begin{bmatrix}3(0)+4(1) & 3(-1)+4(0)\end{bmatrix}[/tex]

[tex]AB=\begin{bmatrix}4& -3\end{bmatrix}[/tex]

Therefore the correct option is B.
